For Boylston, a soloist with the American Ballet Theatre, staying strong is just as important as being flexible. "In ballet, you need a lot of strength in the hips and butt because this area works a lot when pushing off and landing from jumps." One of her favorite moves for toning this area? The classic bridge exercise.

“I feel so lucky to get to move around to music every day and be able to share my art with the audience,” says Boylston. While most of us may be inclined to leave the encores up to her, how about building bridges to a prima ballerina booty?

THE MOVE: THE BRIDGE

Works: Abs, Butt

The Beginner Pose:

The Advanced Pose:

Lie on your back and bend your knees, keeping feet flat. Your shins should be at 90 degrees to the ground. Then, lift hips up so your body is in a straight line. For a more challenging version, extend one leg and then, later, the other. Boylston suggets holding the position for ten seconds, doing ten repetitions, then taking a break and do 2 or 3 more sets of 10, with breaks in between each set. Or, for the more advanced version, she recommends starting with ten regular sets, rest, and then repeat with extending one leg, doing ten with each leg.
